This driver makes use of dmabuffer and viewporter interfaces
to enable efficient display of vaapi surfaces, avoiding
any unnecessary colour space conversion, and avoiding scaling
or colour conversion using GPU shader resources.
This makes use of the new frame acquire/release callbacks to hold on to
hwdec images only as long as necessary. This should greatly improve the
smoothness/efficiency of hwdec interop, by not holding on to them for
longer than needed.
This also avoids the need to pool hwdec mappers altogether.
Should fix#10067 as well, since frames are now only mapped when we
actually use them.
There's really nothing vulkan-specific about this hwdec wrapper, and it
actually works perfectly fine with an OpenGL-based ra_pl. This is not
hugely important at the time, but I still think it makes sense in case
we ever decide to make vo_gpu_next wrap OpenGL contexts to ra_pl instead
of exposing the underlying ra_gl.
libplacebo v198 fixed this properly by adding the ability to flip planes
directly, which is done automatically by the swapchain helpers.
As such, we no longer need to concern ourselves with hacky logic to flip
planes using the crop. This also removes the need for the OSD coordinate
hack on OpenGL.
Render subs at the output resolution, rather than the video resolution.
Uses the new APIs found in libplacebo 197+, to allow controlling the OSD
resolution even for image-attached overlays.
Also fixes an issue where the overlay state did not get correctly
updated while paused. To avoid regenerating the OSD / flushing the cache
constantly, we keep track of OSD changes and only regenerate the OSD
when the OSD state is expected to change in some way (e.g. resolution
change). This requires introducing a new VOCTRL to inform the VO when
the UPDATE_OSD-tagged options have changed.
Fixes#9744, #9524, #9399 and #9398.
This has been the latest stable release for about half a year now. This
version in particular lets us get rid of all the deprecation warnings in
the older code. (See the following commits)
This define was always just a stopgap for that two month period (August
2021 - October 2021) where the bytes_read field in ffmpeg was completely
missing. Before that time, it was a private member in a struct (which
mpv used). Afterwards, it officially became public. Fortunately, the
lack of this field never actually made it into a release, so it could
have only possibly affected people building from the master branch.
Since ffmpeg 5.0 came out recently, and it's been plenty of months since
that two month window, we can go ahead and drop this check. This
finishes up the work done in 78cfeee2b9.
Sidenote: the cached ffmpeg version in the mingw ci were from that time
period when the bytes_read field was missing. The N in the workflow is
bumped to force a full rebuild and fresh clone of ffmpeg.
Changes:
* fixed hangups in the loop function and in some other cases
* refactoring according to @michaelforney's recommendations in #8314
* a few minor and/or cosmetic changes
* ability to build ao_sndio using meson
Changes:
- rewrite to use new internal MPV API;
- code refactoring;
- fix buffers size calculations;
- buffer set to auto;
- reset() - clean/reinit device only after errors;
The AO provides a way for mpv to directly submit audio to the PipeWire
audio server.
Doing this directly instead of going through the various compatibility
layers provided by PipeWire has the following advantages:
* It reduces complexity of going through the compatibility layers
* It allows a richer integration between mpv and PipeWire
(for example for metadata)
* Some users report issues with the compatibility layers that to not
occur with the native AO
For now the AO is ordered after all the other relevant AOs, so it will
most probably not be picked up by default.
This is for the following reasons:
* Currently it is not possible to detect if the PipeWire daemon that mpv
connects to is actually driving the system audio.
(https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1835)
* It gives the AO time to stabilize before it is used by everyone.

Shaderc has been shipping .pc files for almost three years and we all
know of the advantages. If this turns out to be problematic the old checks
can be re-added but I'd like to avoid doing this preemptively.
The GBM supporting nvidia driver doesn't support creating surfaces
without modifiers and using modifiers is more and more recommended as
the right way to do this.
Enumerating modifiers is painfully verbose, but necessary if we are to
allow the driver to pick the best possible one.
This required an upstream API change to implement in a way that doesn't
unnecessarily re-push or upload frames that won't be used. I consider
this a big enough bug to justify bumping the minimum version for it.
Closes#9401
As discussed in #8799, this will eventually replace vo_gpu. However, it
is not yet complete. Currently missing:
- OpenGL contexts
- hardware decoding
- blend-subtitles=video
- VOCTRL_SCREENSHOT
However, it's usable enough to cover most use cases, and as such is
enough to start getting in some crucial testing.
The bytes_read struct member in AVIOContext is now officially public,
so its usage no longer has to be specified as non-compliance with
FFmpeg's ABI/API rules.
That said, unfortunately there was a short period of time between
August 2021 and October 2021 where the struct member did not exist
in FFmpeg's git master, so keep a feature check for it alive for
now to enable building with those versions. Thankfully, no release
version of FFmpeg will be without this field, so it should be
possible to drop this check with time.
Finally, simplify the function in case the struct member is not
found. After all, there is zero reason to iterate through the AVIO
contexts if we cannot get the information we require.
Based on the idea behind emersion's change to drm_info
(869e789a64).
Lets us by default skip devices which are not capable of doing what
the DRM master output requires (not primary devices), as some devices
have card0 actually not be such.
Negative part is that the number given to drm-connector is no
longer a direct mapping against a file name.
TL;DR: use --lua=XXX for pkg-config name XXX, e.g. --lua=lua-5.1 .
For unversioned 'lua.pc', use the name luadef51/luadef52 .
Autodetection remains the same (5.2 names, luajit, 5.1 names).
The old names are still supported, but not auto-detected.
Before this patch, if one wanted to choose a specific lua version when
more than one is installed, then the names were a mess, e.g. 51obsd is
also the name detected on Arch linux, and other (distro) names are
also not unique to a specific distro/platform.
So to ask mpv to choose the package name (specifically, the pkg-config
file name), one needs to look at the mpv sources and find the
(arbitrary) distro name which has the same lua version naming as they
do on their own system, e.g. --lua=51obsd on Arch. This is a pain.
Now we add generic names:
- luadef51/luadef52 - generic pkg-config lua.pc (version is inside).
- lua* - exactly the pkg-config name, e.g. --lua=lua-51 for lua-51.pc
(the names are curated, e.g. --lua=foo won't detect foo.pc).
- The legacy names (e.g. 51deb) are still supported, but undocumented,
and the new generic names take precedence during auto-detection.
The fact that the generic names all start with "lua" has an additional
benefit that it shows right after "lua" at the output of mpv -v,
while the old names start with numbers, so they're first at the list,
making it hard to understand that e.g. "51obsd" is the lua version.
None of these names are actually used at the mpv code. The C code
checks the version using the lua headers (LUA_VERSION_NUM).
Its define (HAVE_FFMPEG_STRICT_ABI) is now utilized in a single
location, where an internal libavformat struct member is utilized.
This struct member is now (after around 10 years) finally removed
from public visibility in FFmpeg's master.
After a review of functionality, the information in bytes_read is
passed onto the demuxer layer, and then utilized for
{cache,hack}_unbuffered_read_bytes. This information is then utilized
for:
1. Calculation of bytes_per_second in demux/demux.c::update_cache,
which fills the information for properties "cache-speed" as well as
"raw-input-rate" (of which stats.lua is the most prominent user).
2. bytes_per_second also affects how often update_cache is called in
addition to the two locations it is called unconditionally in
(read_packet, demux_update).
In other words, the information provided does not appear to control
crucial mpv functionality, but rather its lack would seem to mostly
affect the speed of certain properties updating, or having valid
values. For the former, stream size as well as timed metadata get
updated in update_cache - although the demux layer does throttle
the update of certain things to once per second in that function.
For the latter, "cache-speed" and "raw-input-rate" lose read data
statistics from AVIOContexts opened by the opened FFmpeg AVFormatContext
itself, as opposed to the primary one - which goes through mpv's
stream reading implementation.
By enabling this feature, and disabling this abuse of private API
lets users build mpv by default with the latest master FFmpeg, thus
giving us the breathing room to look into some of the details of
this case, and either decide to:
1. Post a patch to add this information back to FFmpeg proper.
2. Remove or replace this functionality in another manner.
End user impact:
Any IO not handled by mpv itself - but rather by IO contexts newly
opened by the input format - is not visible through the properties
"cache-speed" and "raw-input-rate". Examples of such input formats
are the HLS and DASH readers in FFmpeg.

This brings my scaletempo2 benchmark down from ~22s to ~7s on my machine
(-march=native), and down to ~11s with a generic compile.
Guarded behind an appropriate #ifdef to avoid being ableist against
people who have the clinical need to run obscure platforms.
Closes#8848
Changes:
- code refactored;
- mixer options removed;
- new mpv sound API used;
- add sound devices detect (mpv --audio-device=help will show all available devices);
- only OSSv4 supported now;
Tested on FreeBSD 12.2 amd64.
It's about a year old, and packaged pretty much everywhere that bothers
to package libplacebo at all. Older versions are only a thing on LTS,
which will probably also use older mpv so it works out.
Starting with v2.72.0, libplacebo validates all of its parameters
internally and turns them into function failures. Doing it twice is
awfully redundant, so we can drop the parameter validation.
Also allows us to drop some preprocessor macros.
this drops support for swift <4.1 and with this support for xcode <=9.2.
this was the last setup that is officially working on macOS 10.12.
our old legacy build macOS 10.12 + xcode 9.2 is replaced by macOS 10.13
+ xcode 9.4.1 with swift 4.1. the macOS 10.13 + xcode 10.1 VM is
replaced by the latest macOS 10.14 + xcode 11.3.1 VM. this is the oldest
version officially supported by Apple.
this is in preparations for the following commit.
Should result in: "You manually enabled the feature 'lua', but the
autodetection check failed."
The moved bit of code was probably intended to do that all along, but it
was running too late, so the code that actually checked for Lua didn't
know it was explicitly asked for and quietly disabled it if not found.
Zlib has had a .pc file since 2010, and the default search paths we use
here can break the build on some distros (notably openSUSE Tumbleweed,
which our Travis builds use). Just check pkg-config instead.
remove the hardcoded swift target version and move the version
restriction to configure. this was a bad idea anyway and could lead to
mismatched object files between obj-c and swift. fix travis 10.12 legacy
build.
also update the SDK version parser to handle the new macOS 11 scheme.
Fixes#8281
Based on the implementation of ffmpeg's sixel backend output written
by Hayaki Saito
https://github.com/saitoha/FFmpeg-SIXEL/blob/sixel/libavdevice/sixel.c
Sixel is a protocol to display graphics in a terminal. This commit
adds support to play videos on a sixel enabled terminal using libsixel.
With --vo=sixel, the output will be in sixel format.
The input frame will be scaled to the user specified resolution
(--vo-sixel-width and --vo-sixel-height) using swscaler and then
encoded using libsixel and output to the terminal. This method
requires high cpu and there are high frame drops for 720p and
higher resolution videos and might require using lesser colors and
have drop in quality. Docs have all the supported options listed
to fine tune the output quality.
TODO: A few parameters of libsixel such as the sixel_encode_policy
and the SIXEL_XTERM16 variables are hardcoded, might want to
expose them as command line options. Also the initialization
resolution is not automatic and if the user doesn't specify the
dimensions, it picks 320x240 as the default resolution which is not
optimal. So need to automatically pick the best fit resolution for
the current open terminal window size.
The wl_pointer interface defines button argument as “a button code as
defined in the Linux kernel's linux/input-event-codes.h header file,
e.g. BTN_LEFT.”
We could #define these few buttons ourselves, but there is no system to
test it on, so for now let’s disable Wayland support on them.
This is a call to non-Linux system maintainers, please help test this
backend on your system and report issues you find, or even working
state.
Nobody needs this anymore. If not too many people complain, we'll remove
this completely. Many already consider X11 and OpenGL legacy, so we
don't need TWO X11/OpenGL backends.
On FreeBSD non-POSIX threading functions are in a separate header.
DragonFly and OpenBSD adopted FreeBSD header and extensions.

Previously, EGL as provided by a pkg-config was checked for independently
in several places. The effect this had is that --disable-egl would not
actually disable EGL from the build, as this only affected the "egl" option
relied upon by egl-x11. wayland-gl and egl-drm did their own EGL checks.
By making wayland-gl and drm-egl depend on egl instead, we fix this
behaviour and can simplify egl-helpers a bit, as we can now simply
check whether egl or one of the other features providing some non-pc egl
is enabled, instead of checking every single thing that might be pulling
in egl.
Future work could make the "egl" option just be a catchall for any
EGL implementation, so that brcmegl and angle and Android can piggyback
on the egl option as well.
Ancient Linux audio output. Apparently it survived until now, because
some BSDs (but not all) had use of this. But these should work with
ao_sdl or ao_openal too (that's why these AOs exist after all). ao_oss
itself has the problem that it's virtually unmaintainable from my point
of view due to all the subtle (or non-subtle) difference. Look at the
ifdef mess and the multiple code paths (that shouldn't exist) in the
removed source code.
I wonder what this even is. I've never heard of anyone using it, and
can't find a corresponding library that actually builds with it. Good
enough to remove.
It was always marked as "experimental", and had inherent problems that
were never fixed. It was disabled by default, and I don't think anyone
is using it.
Using mpv without libass isn't really supported, since it's not only
used to display ASS subtitles, but all text subtitles, and even OSD.
At least 1 user complained that the player printed a warning if built
without libass. Avoid trying to create the impression that using this
software without libass is in any way supported or desirable, and make
it fully mandatory.
(As far as making dependencies optional goes, I'd rather make ffmpeg
optional, which is an oversized and bloated library, rather than
something tiny like libass.)
